amount of fuel may be recovered from the ashes by sifting them and returning the combusti'ble substance to the furnace. Ordinarily this substance is in the form of clinkers.

It is the purpose of this invention to provide a clinker and ash collector that can be included in a furnace and by which the ashes and clinkers can be satisfactorily separated.

By employing this improved collector the ashes may be shaken from the clinkers as soon as they have fallen from the furnace grate and the clinker collector can be removed independently of the other elements of the construction, and the clinkers may then be returned to the furnace for further combustion. Likewise the ash collector functions in conjunction with the sifter and can be removed independently. Moreover the entire structure of the clinker and ash collector can be removed as a unit and it is of such structural character that the dimensions may be varied in order that it may be installed in various types and sizes of furnaces.

For a better understanding of the invention reference may now be had to the accompanying drawings forming a part of this specification, of which:

Fig. l is a fragmentary elevation of a furnace having a clinker and ash collector embodying the invention disposed therein;

Fig. 2 is a perspective of a clinker and ash collector;

Fi 3 is a longitudinal section taken substantlally along the line IIIIII of Fig. 1;

Fig. 4 is a fragmentary perspective of an ash box; and,

Fig. 5 is a fragmentary perspective taken substantially along the lines VV of Fig. 3.

In practicing the invention a frame 10 is inserted into a conventional stove or furnace 12 that has an upper door 13 through which fuel, such as coal, is supplied and alower door opening 14 through which theframe is lnserted. An ordinary swinging door 16 having hinges 17 supporting it upon the furnace is ing'18.

The frame 10 is provided with front and rear straps 22 and 23, respectively, which have slots 24 therein for receiving adjustable bolts 25. thatare secured to extensions 27 and 28 at the upper ends of the straps. Upper and lower guides 29 and 30 extending horiprovided with a central draft openzontally from one end of the frame to the other are rigidly secured to the extensions 2728 and straps 2223, respectively, and are in the form of angle bars. Reinforcing bars 31 extend transversely of the frame and connect, the opposite end portion of the guides29. Upper end portions 32 of the extension are bent or flared outwardly for the purpose of supporting oppositely inclined plates 33 that have slots 34 therein for facilitating the adjustment thereof in various positions by properly manipulating screws 36 inserted through the slots and secured to the upper end portions 32. At the rear end of the frame a curved inclined plate 37 constituting substantially a continuation of the plates 33 is secured to the rear extensions 28, and to an ear 38 of a reinforcing strip 39 that extends from the front extensions 27 to the rear extensions 28 and has a curved rear portion 40 from which the ear projects. Suitable connections42 support this strip upon the extensions 27 and 28.

An ash box 43 having a handle 44 secured to the front end thereof is slidably disposed upon the lower guides 30 and is provided with a bail 46 that is pivoted to brackets 47 secured, as indicated at 48, to the inner sides of the central portion'of the box walls. Lugs 49 are provided on the bracket to prevent tipping of the box 'when'it is lifted by the bail.

Likewise an ash sifter 50 shaped substantially similarly. to the ash box is slidably disposed upon the upper guides 29 and is provided with a handle 52 to facilitate withdrawing it from the frame 10. Another handle 53 which is pivoted as indicated at 54 to the sifter is normally adapted to extend through the opening 18 of the furnace door, and by properly manipulating this handle the sifter can be reciprocated upon the guides without opening the door of the furnace. A

bail 56 similar to the bail 46 ispivoted centrally of the sifter.

The lower portion of the sifter has inwardly turned flanges57 and a section. of metallic mesh material 58, constituting a greater portion of the bottom of the sifter, has its edges confined firmly between the flanges 57 and a metallic strip 59 that is substantially complemental to the fianges57 and is disposed about the inner bottom corners of the sifter. Suitable connections 60 extend r mesh material 58 for shifting the ashes.

, From the foregoing description it will be apparent that the frame including the ash boxes and sifter can be inserted as a unit into furnaces of sizes obtaining in ordinary constructions and the plate 33 can be adjusted laterally and upwardly by manipulating the screws 36 in the slots 34. Thus the ashes and clinkers that might otherwise drop outside the frame can be deflected into the sifter. Likewise the height of the frame 10 can be adjusted by properly manipulating the adjustable bolt 25 in the slots 24.. Clinkers and ashes falling from the furnace into the sifter 50 can be agitated by forcing the handle 53 inwardly and outwardly to reciprocate the sifter, thereby causing the ashes to fall into the ash box 43 while the clinkers remain in the sifter. Then the box of ashes may be removed separately, and likewise the sifter containing the clinkers can be withdrawn and the clinkers deposited in the furnace for further burning. As indicated previously the entire sifting operation can be performed without opening the. door of the furnace.

' Although only one form of the invention has been shown and described in detail it will be apparent to those skilled in the art that the invention is not so limited but that various changes may be made therein without departing from thespirit of the invention or from the scope of the appended claims.
